BDeu score

Calculate the local score with BDeu 1 for the discrete case.

Usage

from causallearn.score.LocalScoreFunction import local_score_bdeu
score = local_score_bdeu(Data, i, PAi, parameters)

Parameters

Data: (sample, features).

i: current index.

PAi: parent indexes.

parameters:
  • sample_prior: sample prior.

  • structure_prior: structure prior.

  • r_i_map: number of states of the finite random variable ‘X_{i}’.

Returns
